I get the idea (cyrus)sieve and procmail are equivalent?
I used to get mail for unrecognized users to collect in a master account, rather than bounce. How do I achieve this in cyrus? - now that I've gone all modern.
(Or can I mix procmail and cyrus)


Previous setup :-

pop3->fetchmail->sendmail->procmail to decode->user inboxes->imap

In detail -
- fetchmail - single-mailbox pop3 pickup
- into sendmail
- into one master account,
- then procmail rules would decode the proper local recipient account (rule below) and redirect it there. Or leave other general mail to my domain in the master account.

* for <username@something.net>;*
{
:0
! username
}

Lovely. Nothing bounced back, no mails dissappeared (unless I wanted them to ).


------------------------------------------------------------

New setup :- (with new FC3 standard services)

pop3->fetchmail->sendmail->cyrus->imap


Magically - it seems that intended recipients are being decoded automatically - which is nice. (By cyrus/sieve?)
However - mail for unrecognised users is being bounced, rather than kept in my catchall account.

Does anyone have any pointers?

Many thanks.

Here is the LOCAL_RULE_0 at foot of my sendmail.mc

(pasted from the cyrus howto)

MAILER(local)dnl
MAILER(cyrus)dnl
define(`confLOCAL_MAILER',`cyrus')dnl
LOCAL_RULE_0
R$=N $: $#local $: $1
R$=N < @ $=w . > $: $#local $: $1
Rbb + $+ < @ $=w . > $#cyrusbb $: $1


Who, if anyone, can read this stuff?? I don't have much hope that they can speak English.
What is this doing? - Is it deriving the correct recipient? - Is it bouncing the mail?
Is it recalibrating the Mass of Jupiter.

I dunno!

Until I work this one out (I need to know a lot more about Sieve), here is the workaround I'm going to use.

- Keep PROCMAIL as my local mailer in the Sendmail config (remove references to cyrus)
- Let procmail derive the recipient address as before
- Get the mail to cyrus by using /usr/lib/cyrus-imapd/deliver -a username -m "user/username"
(My cyrus folder sperarator character is '/' - see imapd.conf - unixhierarchysep = yes)

Here is the procmail rule

* for <username@something.net>;*
{
:0
| /usr/lib/cyrus-imapd/deliver -a username -m "user/username"
}

Now to try it.
This is turning into a blog. Sorry!

Edit:
Hang on - Doesn't work yet.

I don't need virtualised users. There are only three of us here!

Things are working nicely - now that I've stopped cyrus, and started dovecot instead.
